The ends of the tubular spool I extend out It is to be understood that Iam not restricted to the specific construction shown anddescribed asvarious modifications can be made thereto within the spirit of theinvention.

What is claimed is:

1. In a device of the character described the combination of anopen-ended tubular spool of non-magnetic -'m'ate rial defining a fluidpassage way, a solenoid coilwound about said spool, a cylindrical casingenclosingsaid coil, said casing having an inturned annular flange abouteach end thereof, a closure disc disposed in each-end of said casingbetween said coil and said inturned flanges, each of said closure discshaving a cenpassageways fornr an integral part thereof, a solenoid"plunger disposed within said tubular "spool, and a valve plunger whichis adapted to "engage the inner end of one of said fluid passagetralaperture therethrough throughwhich said I tubular spool extends, a capremovably secured to each of said closure discs with said flangesinterposed between said caps and said discs, an annular groove in theinner face of each of said caps into which the ends of said tubularspool extend, "coupling means by which said device is interposed in aconduit so that said spool forms .ai-part thereof, .a solenoid plungermounted within said spool,'-a;-valve plunger secured to said. solenoidplunger, and a valve seat formed in one of said caps in which said valveplunger is adapted to-seat to close said fluid passageway.

"2, Inadevice of the character described the combination of a solenoidcoil having'an axial bore therethrough, a cylindrical easing having aninturned annular flange at each end thereof surrounding said coil, "apair of identical closure 'discsf-each having a: central aperture therethrough, one of said discs-being disposed in each end of said casingbetween said coil and the adjacent inturned flange with the centralaperture thereof in alignment with the axial bore in said coil, a pairof identical caps each having a central fluid passageway therethrough,one of said caps being removably secured to each of said closure discswith the adjacent inturned flange securely clamped between the cap andclosure disc, an open-ended tubular spool removably v mounted in saidaxial bore with the ends thereof extending out through the apertures insaid discs :and 'intorgas-tight engagen'ientgwith said caps aroundsaid-fluid passageways-coupling means by which said device is removablyinterposed in a fluid conduit so that said spools and said fluid waysand cut o'if the flow of fluid through said spool carried said solenoidplunger.
